1) the rule:
[tex]\frac{pV}{T}=const;[/tex]
2) according to the rule above the final temperature can be calculated as:
[tex]t_{final}=\frac{p_{init}}{p_{final}}*t_{init}; \ = > \ t_{final}=\frac{100}{300}*95=32.[/tex]
According to the Gay-Lussac's law, as volume is constant the temperature must be decreased to 31.6°C.
What is Gay-Lussac's law?Gay-Lussac's law is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.
The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .The law is given by the formula, V₁/T₁=V₂/T₂, which on substitution gives T₂=95×100/300=31.6 °C.The container in Gay-Lussac's law is considered to be rigid in contrast to the container present in Charle's law.
Thus, as per Gay-Lussac's law, as volume is constant the temperature must be decreased to 31.6°C.

The gas in a balloon occupies 2.25 L at 298 K and 300 kPa. At
what temperature will the balloon expand to 3.50L and 2.17 atm?
Answers
If a gas in a balloon occupies 2.25 L at 298 K and 300 kPa, the temperature at which the balloon expand to 3.50L and 2.17 atm is 345.23K.
How to calculate temperature?The temperature of an ideal gas can be calculated using the following formula:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressureP2 = final pressureV1 = initial volumeV2 = final volumeT1 = initial temperatureT2 = final temperatureAccording to the information given in this question;
P1 = 300kpa = 2.96 atmP2 = 2.17 atmV1 = 2.25LV2 = 3.50LT1 = 298KT2 = ?2.96 × 2.25/298 = 2.17 × 3.5/T2
0.022T2 = 7.595
T2 = 7.595 ÷ 0.022
T2 = 345.23K
Therefore, if a gas in a balloon occupies 2.25 L at 298 K and 300 kPa. the temperature at which the balloon expand to 3.50L and 2.17 atm is 345.23K.

The substance has disappeared after being poured into the water.
The substance makes the water cloudy and then forms a layer on top of the water.
The water remains clear after the substance is stirred into the water with a spoon.

Explanation:
The Scotch broom is an invasive species in California, Oregon and Washington. These shrubs grow quickly after areas that have been cleared of
trees and inhibit reforestation by out-competing native seedling trees. These plants developed a mutation that causes their seed to burst from
their shell when touched by passing animals. As animals brush past these plants, the black dried pods of the Scotch broom explode with a sharp
pop, scattering seeds away from the parent plant.
Which statement below best explains why the Scotch broom is able to out-compete the native plants in that area?
A. Relying on animals to disperse the seeds always results in better reproductive success than other methods of seed dispersion.
B. Specialized seed pods allow seeds to be dispersed farther and into less crowded areas promoting reproductive success.
C. The crackling sound of seed pods exploding promotes reproductive success by attracting the animals that are responsible for scattering
seeds.
D. Genetic mutations have caused the plant to be more resistant to cold temperatures allowing them to survive and reproduce all year
long.
Answers
Based on the illustration, the statement that best explains why the Scotch broom is able to outcompete the native plants in the area would be the specialized seed pods that allow seeds to be dispersed farther and into the less crowded areas.
Reproductive successDifferent organisms have different ways of behaving to ensure the survival of their propagules or offsprings.
In the case of the Scotch broom, the ability of the pods holding the seeds to burst open and catapult the seeds far away from the parent plant is a reproductive strategy to ensure that their seeds are well dispersed.
By doing so, the propagules of the plant will reach new areas where they do not exist before and as such, able to spread quite quicker than the native plants.

in titration, 25 mL of 0.2M NaOH neutralizes 20mL of HCl, what is the concentration of the HCl?
Answers
The concentration of the HCl solution needed to neutralize 25 mL of 0.2 M NaOH is 0.25 M
Balanced equationHCl + NaOH —> NaCl + H₂O
From the balanced equation above,
The mole ratio of the acid, HCl (nA) = 1The mole ratio of the base, NaOH (nB) = 1How to determine the concentration of HCl Volume of base, KOH (Vb) = 25 mLConcentration of base, NaOH (Cb) = 0.2 MVolume of acid, HCl (Va) = 20 mL Concentration of acid, HCl (Ca) =?CaVa / CbVb = nA / nB
(Ca × 20) / (0.2 × 25) = 1
(Ca × 20) / 5 = 1
Cross multiply
Ca × 20 = 5
Divide both side by 20
Ca = 5 / 20
Ca = 0.25 M
Thus, the concentration of the HCl solution is 0. 25 M

What pH do you end up with?
Answers
Explanation:
Good question!
When you react an acid with a base,the pH of the product is determined by the concentrations of the reactants (the acid and the base)
If both reactants (acid and base) are strong,the pH of the product is 7
If the acid is stronger than the base,the pH of the product will be less than 7
If the base is stronger,the pH of the product will be greater than 7
